* [svn-r11022] Purpose:Quincey Koziol2005-07-051-18/+18
| | | | | | | | | | | | | | | | | | | | Bug fix & code cleanup Description: Don't unmount child files from a parent file if the parent file is being held open by an object. Also, moved the mounting routines into their own source file and the superblock routines into their own file also. Solution: Moved the code for unmounting child files down in the H5F_close routine and also add checks to the file and group mounting code to unmount child files when the last object holding open a file closes. Platforms tested: FreeBSD 4.11 (sleipnir) h5committest

* [svn-r10682] Purpose:Xiaowen Wu2005-04-271-7/+7
| | | | | | | | | | | | | | | | | | Slight modifications. Description: Several constants related to the H5Pset_scaleoffset interface are added into H5Zpublic.h. Test cases that calls H5Pset_scaleoffset needs slight modifications. Solution: Use the defined names when calling H5Pset_scaleoffset instead of using numerical numbers. Platforms tested: heping, shanti Misc. update:
* [svn-r10674] Purpose:Xiaowen Wu2005-04-261-29/+472
| | | | | | | | | | | | | | | | | | | | New feature. Description: The scaleoffset filter has been implemented to to compress floating-point data (single precision and double precision) using D-scale method from GRIB. Solution: Test cases for float and double datatypes are added according to the change of scaleoffset filter. Situations of fill value defined/undefined are tested. Platforms tested: heping, shanti, copper Misc. update:
* [svn-r10603] Purpose:Xiaowen Wu2005-04-141-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | Bug fix. Description: The nbit filter test case (compound datatype with no-op field) can not pass the daily test on heping and eirene when the enable-production option is set with configure and PGI compiler is used. It will generate segmentation fault. Solution: It was found that the seg fault disappears when adding a new index variable in the test case and using it instead of using an existing index variable twice during initialization. This does not make much sense since previous codes is logically equivalent to the changed codes. So, some other factors beyond the test case codes may have caused the problem. Platforms tested: heping Misc. update:
* [svn-r10569] Purpose:Xiaowen Wu2005-04-071-10/+219
| | | | | | | | | | | | | | | | New feature. Description: The N-Bit filter needs a test case for no-op datatypes. Solution: A test case was added to test a compound datatype with N-Bit fields and no-op fields. Platforms tested: heping, shanti Misc. update:
* [svn-r10395] Purpose:Xiaowen Wu2005-03-241-1/+1
| | | | | | | | | | | | | | | Bug fix. Description: One test case of scaleoffset filter has fill value too large for int. Solution: Change the value to be within the range of int. Platforms tested: heping Misc. update:
* [svn-r10385] Purpose:Xiaowen Wu2005-03-231-28/+304
| | | | | | | | | | | | | | | | | | | New feature. Description: The scaleoffset filter is now complete for compressing integers. All previous bugs have been fixed. The filter does not compress floating-point at present. Solution: Update test cases for the scaleoffset filter. Two for integer types and one for floating-point (even though the filter does not compress). The two test cases for integer type tests situations where fill value is defined and undefined for the dataset. Platforms tested: heping, copper, shanti Misc. update:
* [svn-r10081] Purpose: Some Kind of VerificationRaymond Lu2005-02-241-0/+1
| | | | | | | | | | | | | | | | | | Description: The library didn't handle incorrect hardware conversion for datatype. It simply did convert to incorrect data if any hardware didn't handle correctly. Solution: During configuration, incorrect hardware conversion is detected and some macros are defined. Use these macros to decide whether to register hardware conversion in H5T.c. If no hardware conversion function is registered for certain pair of datatypes, software conversion function will be used as the conversion path. Although slower than hardware conversion, we're more confident software conversion is accurate. So in one sentence to describe library's behavior, if some hardware conversion doesn't work well, software conversion will be used instead. Platforms tested: h5committest and fuss. Misc. update: some changes to configure's comments.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug Fix/Code Cleanup/Doc Cleanup/Optimization/Branch Sync :-) Description: Generally speaking, this is the "signed->unsigned" change to selections. However, in the process of merging code back, things got stickier and stickier until I ended up doing a big "sync the two branches up" operation. So... I brought back all the "infrastructure" fixes from the development branch to the release branch (which I think were actually making some improvement in performance) as well as fixed several bugs which had been fixed in one branch, but not the other. I've also tagged the repository before making this checkin with the label "before_signed_unsigned_changes". Platforms tested: FreeBSD 4.10 (sleipnir) w/parallel & fphdf5 FreeBSD 4.10 (sleipnir) w/threadsafe FreeBSD 4.10 (sleipnir) w/backward compatibility Solaris 2.7 (arabica) w/"purify options" Solaris 2.8 (sol) w/FORTRAN & C++ AIX 5.x (copper) w/parallel & FORTRAN IRIX64 6.5 (modi4) w/FORTRAN Linux 2.4 (heping) w/FORTRAN & C++ Misc. update:

| | | | | | | | | | | | Fix SZIP filter to dynmically detect encoder. Description: Solution: See: http://hdf.ncsa.uiuc.edu/RFC/SZIP/Szip_dynamic_12_Oct.pdf Changes to library tests, contingent on detecting SZIP encoder.
* [svn-r9155] Purpose:Quincey Koziol2004-08-251-0/+106
| | | | | | | | | | | | | | | Bug fix (sorta) Description: Change reading of "missing" chunks from datasets with undefined fill values to not overwrite the application buffer with random garbage from memory. Note that this is almost the same, since whatever garbage the application had in those locations will still be there... Platforms tested: FreeBSD 4.10 (sleipnir) IRIX64 6.5 (modi4) h5committested
* [svn-r8962] Purpose:Quincey Koziol2004-07-281-0/+52
| | | | | | | | | | | | | | | Bug fix Description: Allow I/O on extendible chunked datasets with (currently) zero-sized dimensions to proceed harmlessly instead of dumping core on an assertion. Solution: Removed assertion and added checks to avoid problem situation in H5TB_end Platforms tested: FreeBSD 4.10 (sleipnir) w/ & w/o parallel Too minor to require h5committest
* [svn-r8916] Elena Pourmal2004-07-211-4/+11
| | | | | | | | | | | | | | | | | | | | | Purpose: Improvement Description: HDF5 Library set pixels_per_scanline parameter to the size of the chunk's fastest changing dimension. As a result, fastest changing dimension of the chunk could not be bigger than 4K and smaller than pixels_per_block value and szip compression couldn't be used for many real datasets. Solution: Reworked algorithm how HDF5 sets pixels_per_scanline value; only chunks with the total number of elements less than pixels_per_block value are rejected. There is no restriction on the size of the chunk's fastest changing dimension anymore. Modified the test according to the new algorithm. Platforms tested: verbena, copper, sol Misc. update:

* [svn-r8781] James Laird2004-07-011-27/+219
| | | | | | | | | | | | | | | | Purpose: HDF5 now supports SZIP with no encoder. Description: SZIP can be configured to have both encoder and decoder or just to have the decoder. HDF5 can now query the configuration of any filter, and will throw errors if users try to write using a filter with encoding disabled. Solution: Added H5Zget_filter_info function, changed API for H5Pget_filter and H5P_get_filter_by_id. See SZIP RFC. Platforms tested: Copper (fortran, C++, parallel), Sleipnir (C++), Arabica (fortran, C++), Verbena (fortran, C++) Misc. update:
* [svn-r8600] Purpose:Quincey Koziol2004-05-311-53/+68
| | | | | | | | | | | | | Code optimization Description: Don't recompute the internal index value for looking up the chunk in the hash table, just use the value already computed from iterating through the chunks. Platforms tested: Solaris 2.7 (arabica) FreeBSD 4.9 (sleipnir) w/parallel
* [svn-r8590] Purpose:Quincey Koziol2004-05-271-0/+2
| | | | | | | | | | | | | | | | | | | | | Code optimization & bug fix Description: When dimension information is being stored in the storage layout message on disk, it is stored as 32-bit quantities, possibly truncating the dimension information, if a dimension is greater than 32-bits in size. Solution: Fix the storage layout message problem by revising file format to not store dimension information, since it is already available in the dataspace. Also revise the storage layout data structures to be more compartmentalized for the information for contiguous, chunked and compact storage. Platforms tested: FreeBSD 4.9 (sleipnir) w/parallel Solaris 2.7 (arabica) h5committest

| | | | | | | | | | | | | | | | | | | new library function H5Pdelete_filter deletes one or all filters from a dataset creation property list this was done for the NONE option of h5repack, added tests for this feature added a test for the new function in /test/dsets.c Description: Solution: Platforms tested: linux solaris AIX Misc. update:
* [svn-r8038] Purpose:Quincey Koziol2004-01-081-0/+88
| | | | | | | | | | | | | | | | | | | | Bug fix Description: When two property lists are compared, the H5Pequal routine was just comparing the raw information for the property values. This causes problems when the raw information contains pointers to other information. Solution: Allow a 'compare' callback to be registered for properties, so that a user application get perform the comparison itself, allowing for "deep" compares of the property value. This was exported to the H5Pregister & H5Pinsert routines in the development branch, but not the release branch. Platforms tested: FreeBSD 4.9 (sleipnir) h5committest
* [svn-r8007] Purpose:Quincey Koziol2003-12-311-0/+55
| | | | | | | | | | | | | | Bug fix Description: Range check the szip 'pixels per block' against the chunk size of the dataset when attempting to create a new dataset, since the szip library requires the PPB to be at least the size of the fastest changing dimension in the chunk.

* [svn-r6825] Purpose:Quincey Koziol2003-05-071-39/+70
| | | | | | | | | | | | | | | | | | | | | | | | | New feature/enhancement Description: Chunked datasets are handled poorly in several circumstances involving certain selections and chunks that are too large for the chunk cache and/or chunks with filters, causing the chunk to be read from disk multiple times. Solution: Rearrange raw data I/O infrastructure to handle chunked datasets in a much more friendly way by creating a selection in memory and on disk for each chunk in a chunked dataset and performing all of the I/O on that chunk at one time. There are still some scalability (the current code attempts to create a selection for all the chunks in the dataset, instead of just the chunks that are accessed, requiring portions of the istore.c and fillval.c tests to be commented out) and performance issues, but checking this in will allow the changes to be tested by a much wider audience while I address the remaining issues. Platforms tested: h5committested, FreeBSD 4.8 (sleipnir) serial & parallel, Linux 2.4 (eirene)
